Improvements in Mortaring Devices; Aand we do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a mortar device 4 and more particularly to the class of devices for usepin mortaring hollow cement building blocks when constructing walls, partitions or the like.

The primary object of the invention is the provision of a device of this character -in which mortar may be conveniently and rapidly applied to a hollow building block so that the said mortar will notfall into the air spaces or hollow -portions of the block when being applied thereto in the .erection of a building wall, partition or the like. f Another object of the invention is the rovision ofa device of this character in w ich mortar may be applied in a uniform and even manner to hollow building blocks and that is capable of adjustment so that it may be used with varyin sized 'hollow blocks when constructing a uilding wall or other masonry.

A further object of the invention is the provision of a device of this character which is simple in construction, thoroughly reliable and efficient in operation, and inexpensive in the manufacture.

In the drawings, accompanying and'form- ,ing part of this specication is illustrated the preferred .form of embodimentl of the invention, which to enable those skilled in the art to practise the invention, will be set forth at length in the ollowingdescription, while the novelty of theinvention will be, pointed out in the claims succeeding-the de- I seription, it being understood of course, that minor changes, variations, and modifications may be made such as come properly within the scope of the appended claims without de arting from the spirit of the invention.

Similar reference characters indicate cor'- responding parts lthroughout ythe several views in the drawings.

p Referringto the drawings, 10 designates l generally va mortaring device constructed in accordance with the invention, said device comprising a skeleton frame having spaced parallel side :bars 11 bent at one end of the frame to form outwardly diverging an/gularly disposed terminals 12, Figs. 5 'and 6. Bolted :to eachof the terminals 12 is an upright 13. These -u'prights are provided with elongated slots 14 respectively and slidably mounted in each of the slots is an adjustable binding bolt 15 'by means of .which vertical bars 16 are -adjus'tably secured to the up rights I3. Thesebars 16 have their upper ends lbent inwardly toward each other so as to form right .angular extensions 17, which latter are providedl with elongated slots v1'8 Fig. 1. Secured to the angular vextensions 17 by means of bolt fasteners 19 engaged in the slots 18 is an angular cross connecting plate 20, said plate having one arm disposed fiat-f upon the angular extensions 17 and pro,

vided with a slot 20 in which the `boltfasteners 19 rare also -engaged so that the side bars l1 maybe spread apart or 'brought into close relation with each other.

Secured to the opposite ends of the side bars 11 by `fasteners 21 are inwardly direct- 'l ed slotted members 22 respectively. .These members are disposed at right-angles to the side bars and have engaged in their respective slots binding 'bolts 23, by means of' which al slotted cross connecting plate 24 isl adj-ustablyv connected to the members 22. As .the binding bolts 23 engage in the slots o-respective members 22 and in the slot of.

the cross connect-ing plate4 24 it v,will be aparent that the side bars may be moved away om and toward each other at that point in a similar manner with respect to the other cross connecting plate 20 at the opposite end ofthe frame.

Connected to the cross connecting plates 20 and 24 of the frame and disposed longitudinally of the latter between the sidepbars are adjustable slats comprising overlapping sections 25 and 25'. The ends of the sections 25 and 25 of each slat are bentrnpwardly at right-angles as at 26and adjustably secured to the cross connecting plate 20. This adjustable connection between the plate 20 and the sections of each slat is had by adjustably connecting the upwardly bent rightangular extremities 26 of the slat sections to slotted 'terminal plates 27 by means of bolts 27 and in turn adjustably connecting said plates 27 by binding bolts 28 to the slot-ted rightangular portion 29 of the cross connecting plate 20. By this construction the sections of each slat may be adjusted laterally toward and away from each other and the bolts 27 moved toward and away from the free ends of the angular bent portions 26 of the slats.l It will be noted that by bending the slat sections 25 and 25 upwardly as at 26 such upwardly bent portions will engage the exposed end of a previously laid block during the use of the device and thus aid in correct-ly positioning the device for the application of vmortar upon which to lay the next block.

The overlapping sections of the slats are held adjnstably connected by fasteners 30 and each section has its outermost edge bent downwardly to form a depending flange 31, which extends throughout the length of the section and these flanges of the sections ot each slat converge toward each other so as to not disturb the mortar when placed in the spaces between the slats upon hollow building blocks, as the frame is being lifted or removed therefrom. l Secured to and rising from the cross connectingplates 20 and 24: are loop handles 32, which latter are adapted to be gripped by an operator when the mortaring device is in use.

To spread mortar in the spaces between the slats on the frame there is provided a trowel or spreading device 33, having a handle 34, which enables an operator to manipulate the said device when laying the mortar upon the hollow building blocks.

In operation, the mortaring device is positioned upon the upper faces of adjacent hollow building blocks 35, so as to have the overlapping sections of the slats 25 cover or lie across the air spaces 36,in the building blocks and then mortar is laid upon the iframe so as to lill in the spaces between the y l bility of the mortar filling the air spaces 36,

in the said building blocks while constructing a wall or partition.

From the foregoing, the construction and operation of the invention will be clearly apparent without the necessity of a more extended explanation and therefore the same has been omitted.

What is claimed is.-

1. A device of the class described comprising a skeleton frame having side bars, means connecting the opposite ends of the side bars to permit adjustment thereof toward and away from each other, and substantially inverted U-shaped slats adjustably secured to said means, each of said slats being' formed of two sect-ions adjustably overlapping each other to permit'widening and narrowing of the slats, the said slats being normally spaced from each other.

2. A mortaring device comprising a skeleton frame having spaced parallel longitudinal side bars, the same being bent at one end of the frame to provide outwardly diverging angularly disposed terminals, uprights secured to said terminals, vertical side bars adjustably secured to the uprights, a cross connecting plate adjustably secured to corresponding ends of the longitudinal side bars, a handle secured to said cross connect-l ing plate, subst-antially inverted U-shaped slats arranged between said longitudinal and vertical side bars and adj ustably connected at one end to the cross connecting plate, and an adjustable connection between said slats at their other end.

In testimony whereof, we ailix our signatures in presence of two witnesses.
